TYPEWRITING MACHINE.

Application filed October 7, 1921. Serial No. 505,988. I

To all whom it may concern:

Be it known that I, J Antes C. ANDERSON, a citizen. of the United States, residing in Phoenix, in the county of Oswego and 'State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following 1s a specification. I

This invention relates to work-positioning devices for ty ewriting machines.

The main 0 ject of the invention is to provide improved means for guiding a short sheet or card to the platen and to facilitate rapid positioning of the sheet to a plurality of line-space positions. Other objects are to provide simple and effective means for this purpose economical to manufacture and readily applicable to machines in use.

In carrying out the invention, an aligning table with upstanding side members at the proper distance apart to receive the worksheet or card is mounted above the platen. The upstanding members or sidesare also provided with ledges or flanges overhanging the table so as to tend to prevent movement of the sheet away from the table, and one of the, members is also supplied with a resilient arm or finger extending across the platen at the printing line so as to hold the card or laten. Obviously, two resilient arms may e provided,

one for each side member. Preferably, however, only one is used so as to enable ty ing to be effected close to the other edge of the sheet. The table may also be provided with upper edge-gaging means at its upper edge.

As herein disclosed, the invention is illustrated as adapted for use in filling out 'a card on which two lines of entries are to be made. The card maybe placed in position on the table in different ways but preferably by bending or. bulging the card forwardly along its central line to enable its edges to be passed back of the overhanging ledges so as to spread out thereunder when the'middle portion of the card is moved against the table. Preferably the top of the type-bar with the use of the segment for gaging purv segment is used as a lower edge gage to posi tion the card for writing on the upper line thereof, and the usual wing-scales are omitted since, if present, they would interfere It is also proposed to use the card with a tally-strip device. After the upper line on the card is typed, the line-space and car- Image-return lever is operated and the tallystrip advanced. The card or sheet tends to advance with the tally-strip, but, in case'this movement is not completed, the card may be grasped by the operator and positioned by means of the upper edge-gaglng means on the aligning table.- To avoid interference with the fingers in handling the cards, the aligning. table may be provided at its upper edge with a recess of, sufficient size to permit insertion of the card to its lower position without interference with the fingers.

Other features and advantages will hereinafter appear. 4

re 1 isa front view, showing the Figure 2 is'a sectional side view, showing the card'with its lower edge gaged by the type-bar segment.

Figure 3 is a detail perspective view of one end of the aligning table.

Figure 4 is a sectional side view similar to Figure 2, showing the .card with its- 'upper edge gaged at the upper edgeof the aligning ta e.

Figure 5 is a sectional view of the align ing table or chute, showing the manner in which the card is bent in placing it in the chute. i

Upon the depression of keys, not shown. type-bars 11 will be swung upwardly and rearwardly to cause types 12 thereon to strike a platen 13 of which the axle 13 1s journaled in the ends 14 of the platenframe. The proper'position of the types at the printing point is obtainedby means of a type-bar guide 15 which is secured to the front of a type-bar segment 16 and extends above the horizontal upper surface of the latter. I 'Mounted on the ends 14 of the platenframe are left and ri ht-hand brackets 17 and 18, respectively, etween which 'extend rods or shafts 19 which passthrough slots 20.of brackets or plates 21 mounted on a. rod 22, connecting the ends 14; of the platen-frame, and prevent the brackets 21 from turning about said rod 22.

Each of the brackets-21 is provided at its front with a lug 23 extending inwardly therefrom, and these lugs serve to support an aligning table or plate 24 secured to the front of bars 25 secured to said plate and held on the lugs 23 by headed studs 26 passing through slots 26* in the ends of bars 25 and secured to the lugs 23. Secured to the table or plate 24 by any suitable means, such as screws 27 at a suitable distance a art to receive therebetween a card of the slze to be used, are two side-edge guides 28 and projecing inwardly from the tops of these guides are ledges or flanges 29. Tt will'be seen that the structure ust described constitutes a card-inserting chute.

The ledges 29 are cut away adjacent the upper edge of the table 24 so as to provide openings 30 to permit a card or sheet to be inserted over upper edge gages or lugs 31.

The guides 28 and the ledges 29 may be unitary in structure or may be separate and fastened together in any suitable manner, as by means of screws or by brazing. The right-hand guide is also provided with a re silient arm or finger which may be in the form of a s ring 32 to engage the platen 13 at the prin in line.

The rear no or shaft 19, Figure 2, may serve to support the delivery roll of a tallystrip 33, which, after passing around the platen 13 and a ide 34, is wound upon the upper rod or s aft 19 on which is fixed a ratchet-wheel 35. Upon operation of the usual line-space and carriage-return lever 36, a slide 37 will bemoved to the rear, and, by means of a pawl, not shown, will actuate the ratchet, 38 fixed on the platen-axle 13 and actuate the platen. The movement of the slide 37 will cause a link 39 connected thereto to operate an arm 40 and also, by means of a pawl 41 loosely mounted ona pivot 42 connecting the link 39 and the arm 40, to actuate the ratchet-wheel 35 and advance the tally-strip.

The operation is preferably as follows:

Each card 43 to be filled out is grasped at the top and bent or bulged forwardly at its middle line from top to bottom, so that the sides will extend to the rear and the in Figure 2, the card is of such size that,

when gaged in this manner, the upper of the two lines to betyped will lie at the printing line. To enable gaging of the lower edges of the cards in this manner, the usual wing-scales are omitted. Tt should be unneoaeio derstood that other gaging means for the lower edge of the card may be provided.

Entries may then be typed upon the card through a usual ribbon, not shown, and a carbon copy made on the tally-strip 33 by means of a carbon-sheet (not shown), posimeans. To enable the card 43 to be grasped at the upper edge when in its lower position, the table 24 is provided with a recess 44 at its upper edge, this recess also serving to facilitate the downward movement of the card when originally inserted.

After the typing on the lower line of the card is completed, the card may be grasped at its upper edge and withdrawn from the chute, another card being inserted in the same manner. This operation may be repeated until all of the cards have been filled out.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
